How Langley is built

Langley's houses by when they were built Ten house shapes, one for each tenth of Langley's 42,165 houses. Before 1961: 4%, 1961–1990: 37%, 1991–2000: 18%, 2001 or later: 41%. Older houses glow hotter.

Each house stands for one in ten of Langley's 42,165 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

Why the design temperature matters in Langley

−6.3°C is the 9th-mildest design temperature of the 70 cities we cover. The F280 calculation works out how much heat each room loses on that design day, from the house's actual walls, windows, air leakage and ceiling insulation.

With a design day that mild, a heat pump sized to the calculation can carry most or all of a typical Langley house's heating load, which makes sizing it right, rather than oversizing it, the main job.

In the Vancouver area, 32% of households heat mainly with a forced-air furnace, 31% with electric baseboards, 12% with a boiler and radiators and 5% with a heat pump; natural gas is the main heating energy for 42% of households and electricity for 39% (Statistics Canada, 2023).

Why skipping it costs money

Contractors who size by square footage routinely oversize. An oversized heat pump costs more to buy, cycles on and off, dehumidifies poorly in summer and wears faster. An undersized one leans on backup heat. The F280 report is the evidence either way, and it's worth having before you compare quotes.

What it costs

About $150–$400 as a standalone calculation (a September 2026 planning range; quotes vary). Many energy advisors bundle it with an EnerGuide evaluation, which also gives the calculation measured air-leakage data instead of an assumption.

NRCan-licensed service organizations serving Langley

Many energy advisors also do room-by-room CSA F280 calculations for an extra fee; HVAC designers do them too. Ask for the F280 report itself, not just an equipment recommendation.
